The invention provides a fake-licensed ship identification method and system, and the method comprises the steps: obtaining a ship automatic identification system (AIS) data sequence belonging to the same ship identification information, arranging the AIS data in the AIS data sequence according to the receiving time, wherein the AIS data comprise dynamic information; based on dynamic information contained in AIS data in the AIS data sequence, determining a plurality of dynamic trajectory branches, and determining the category of each dynamic trajectory branch, wherein the category comprises fake-licensed ship branches; if it is judged that the dynamic trajectory branches include fake-licensed ship branches and the number of the fake-licensed ship branches is larger than 1, determining that the ship identification information is identification information of the fake-licensed ship. According to the fake-licensed ship identification method provided by the invention, external factors such as weather and distance can be overcome, the fake-licensed ship can be effectively identified, a perfect ship number identification monitoring system does not need to be erected, the identification cost of the fake-licensed ship is reduced, and an AIS data sequence is adopted, so that the identification accuracy of the fake-licensed ship is ensured.

    本发明提供一种套牌船识别方法及系统,该方法包括:获取属于同一船舶标识信息的船舶自动识别系统AIS数据序列,AIS数据序列中各AIS数据按接收时间排列,AIS数据包括动态信息;基于AIS数据序列中各AIS数据包含的动态信息,确定若干动态轨迹分支,并确定每个动态轨迹分支的类别,所述类别包括套牌船分支;若判断获知若干动态轨迹分支中包括套牌船分支且套牌船分支的数量大于1,则确定所述船舶标识信息为套牌船的标识信息。本发明提供的套牌船识别方法能够克服天气和距离等外界因素,有效识别出套牌船,并不需要架设完善的船号识别监控系统,降低了套牌船的识别成本,而且采用AIS数据序列,保证的套牌船识别的准确性。
